ROBERT O.- DANIEL, OF COMANOHE, TEXAS, ASSIGNOR OF ONE-THIRD TO J. E. JAMESON, OF

` DALLAS, TEXAS.

WRENCH.

To all whom it may concern:

Be it known that I, ROBERT O. DANIEL, a citizen of the United States, residing at Comanche, in the county of Comanche and State oi Texas, have invented a new and useful Wrench; and I do hereby declare the following to be a full, clear, and exact description of the invention, such 'as will enable others skilled 4in the art to which it appertains to make and use the same.

This invention pertains to a new and useful wrench,

and it has for its object to provide a strong, durable and efficient device of this character which may be set readily at the desired adjustment, to fit the size of nut to be unscrewed. f

A further object is to provide a wrench having a mov- L5 able wedge-shaped member, to coperate with a ver-` tically movable locking member, both being carried within .a housing, which is integral with the movable jaw of the wrench. Said wedge-shaped member is d esigned to reciprocate through the action of the screw, l() which is threaded therewith and is also swiveled in the wall ofthe said housing, as will be clearly manifest.-

With these and other objects in view, the invention consists in the novel construction and arrangement of parts, hereinafter described and shown and particu- !5 larly pointed out in the appended claims.

In the drawings, Figure l is a side elevation of the wrench, illustrating the movable jaw thereof, in section. Fig. 2 is an enlarged plan view of the locking member. p

l0 Referring to the drawings, l designates an immovable jaw of the improved wrench. This immovable jaw has integral therewith a shank 2, one face of which is provided with serrations 8, as clearly shown; the' Specification of Letters Patenti Application filed April 10,1907. Serial No. 367,412.

rations 9a which are adapted to engage the serrations 8 of the said shank, that is, when the locking member is forced upward as will be clearly understood. The locking member is provided with a lower'inclined sur- 45 face b, which cooperates with the inclined surface c, of the wedge-shaped member; by the cooperation of these inclined surfaces, the locking member is forced upward so as `to engage the serrations of the shank and is also provided with an angle portion l0, against which the beveled portion d, of the member 6 abuts, that is, when it is moved toward the immovable jaw. When the member 6 is moved toward the immovable jaw, thereby causing the bevel d to contact with the portion l0, the said-locking member will have a slight oscillation to free the serrations 9a from the serrations 8 of the shank, as will be clearly understood.

To cause the member 6 to be reciprocated,. a screw 7 is threaded in connection therewith as shown in the drawings, and by the rotation of the said screw, the member 6 will be moved, for the reason that the said screw is swiveled as'at e, in the wall of the said housing,

yso as to prevent longitudinal movement thereof.

Having thus described the invention, what is claimed as new and useful by the protection of Letters- Patent, is:

A wrench having a rigid jaw and a shank portion thereof having sel-rations upon one of its faces, a movable jaw mounted upon said shank, said movable jaw` having a honsngga locking member located therein, said locking member having an under inclined surface and an ,angled end portion, said locking member having serrations to engage serrations of the shank, a screw-operated wedgeshaped member having its upper face oppositely inclined, one of the inclinations of the Wedge shaped member designed to engage the inclined surface of the locking member while the other inclination is adapted to engage the angled end, portion so as to oscillate the locking member, as specified.

In testimony whereof I have signed my naine,to this specification in the presence of two subscribing witnesses.
